CARL EHIL BAARSEN, OF BERGEN, NORWAY.

Lite-BOAT, 36C.

SPECIFICATION forming part of Letters Patent No. 696,621, dated April 1,1902-.

Application filed March 15. 1901. Serial No. 51,314. kNo model.)

To all whom it may concern:

Be it known that I, CARL EMIL BAARSEN, a subject of the King of Swedenand Norway, residing at Bergen, Norway, have invented new and usefulImprovements in Life-Boats, of which the following is a specification.

The object of my invention is to provide a boat of special shape incombination with a special arrangement of air-chambers and ballast tank.It has been shown by several thorough trials that boats provided with myimprovements possess in a particularly high degree the self-rightingproperties which are especially desirable in the case of life-boats andfishing-boats.

The improvements described can be applied to any boat; but in theaccompanying drawings the invention is shown as applied to a Norwegiannorlandish fishing boat-a so-called ottring.

In the accompanying drawings, Figure 1 is a side view of a boatconstructed according to my invention. Fig. 2 is a plan, and Figs. 3, 4,5, 6, and 7 are sections, of the boat on its different frames.

The keel of my improved boat is proportionally short, deepest midshipsand higher fore and aft, and the bottom of the boat is deeper midshipsthan fore and aft. By this construction the boat is very easy to handle.

A further and most important feature of my invention is the specialarrangement of the air-chambers. A Norwegian norland boat has the defectthat when capsized it immediately turns bottom upward and remains inthat position, the cause being that the boat is long, narrow, and low.When a Norwegian lister boat or a bark is upset, it will not turn over,as the norland boat, but is filled with water and goes to the bottom,owing to the boat being short, broad, and deep.

According to myinvention the air-chambers are placed beneath, say, fivethwarts in such a manner that the highest or deepest end of the chamberfollows the frame from the thwart down to the bilge of the boat and goesfarther in a sloping direction inidships and up under the thwart. Allchambers should be made of iron plates.

The advantage of myimproved boat is that should it be upset it will notturn over with turn the boat over.

the keel upward, but will rest with the sails on the water. Theair-chambers at the stem and stern prevent the boat from turning withthe keel upward. The side chambers keep the boat from sinking, and if bya quick action of the crew the shroud is cut to windward the mast willfall overbaard and the boat immediately right itself.

Should the boat be upset and a breaker throw the boat around with thekeel upward, the chambers placed in the stem and stern will right theboat. It the crew are secured or fastened in the boat,-theywill besaved.

The chambers will carry the boat full of water and sufiicientsailing-ballast. If fixed ballast is preferred, the boat will be safer,because the air-chambers will then naturally act upward and the ballastdownward, and a breaker will then scarcely have power to Under suchcircumstances the loose ballast will roll out of the boat and lightenit, so that the air-chambers and the fixed ballast will more quicklyright the boat.

Fig. 1 illustrates the form of the boat above described, with its curvedkeel a, which also allows for the great depth of the boat midships.

From Figs. 3, 4, 5, 6, and 7 it will be seen how the air-chambers b bare arranged under each thwart in two parts, while the air-chambers c inthe stem and stern may be in one part, as shown in Fig. 1. Theair-chambers b b may communicate with each other, thereby forming asingle easing across the boat under the thwarts.

Figs. 2 and 7 show the arrangement of a bal-' last-tank d in the bottomof the boat. This tank is placed midships and can be filled with waterassoon as the boat is launched by open ing a stop-cock e in the bottom ofthe boat. The stop cock is situated on one side of the keel and may beopened and shut by a rodf, which passes through a pipe g and is providedwith a handle h, arranged under the thwart.

It is the special form of the boat, in combination with the arrangementof the air-chambers partly just underneath the thwarts and partly in thestem and stern of the boat, which give the boat its self-rightingproperties, and it is the combined arrangement of these parts,substantially as described and rod and handle, said ballast-tank beingin shown, which forms the object of this inventhe bottom of the boat andcontrolled bysaid tion. stop-cock, substantially as described.

Having now described my invention, what In witness whereof I havehereunto set my 5 I claim as new, and desire to secure by Lethand inpresence of two witnesses.
